The proper fix would be to initialize the 'heartbeat' variable with 0,
set wdt->timeout to DEFAULT_HEARTBEAT, and to keep passing 'heartbeat'
to watchdog_init_timeout(). That used to be done but was explicitly
changed in an earlier commit, presumably on purpose. I am not inclined
to accept a (partial) revert unless the author of commit 5527483f confirms
that this is acceptable and desirable. Otherwise we'll just end up in an
edit war, which I really don't want to get into.
